What is the sterilizing concentration requirement of ozone for water?

The most economical operation is ozone water soluble concentration, and the reaction time is 4 minutes. Ozone is a gas, and only by dissolving ozone into water, so that the water contains a certain concentration of ozone, and maintaining a certain reaction time, can the purpose of sterilization and disinfection be achieved. There are several commonly used ways to mix ozone with water, such as bubbling method, jet method, and mixing pump.

In order to make the water reach a certain ozone concentration, in addition to the ozone generator.

There is sufficient ozone production and concentration, and the gas-liquid mixing efficiency also needs to be ensured. Recommended ct values for the ozone industry.

, c is the ozone water soluble concentration (mg l), t is the reaction time (min).

Concentration of ozone in water:

The ozone solubility in water applications is between. The low value is used as the minimum concentration required for water disinfection and purification, and the high value is used as the achievable concentration value of "ozone water disinfectant".

Tap water ozone purification, the solubility value of the international conventional standard, is maintained for 4 minutes, that is, the CT value is.

The residual ozone concentration in the water is kept at the effect for 5 10 min to achieve the purpose of disinfection.

When the solubility of ozone in mineral water is there, it can meet the requirements of sterilization and quality preservation. A reasonable amount of ozone is:

The ozone solubility value that should be reached for bottled water treatment requires that the ozone dosage should meet the amount of 2g O for 1m of water. According to practical experience, it is easy to reach the concentration of ozone when the concentration is higher than 8 mg l.

Ozone (O), also known as superoxide, is an allotropic form of oxygen (O), and at room temperature, it is a light blue gas with a special odor. Ozone is mainly distributed in the stratospheric atmosphere at an altitude of 10 50 km, with maximums ranging from 20 to 30 km.

Ozone is extremely oxidizing and has a redox potential second only to fluorine, which is mainly used in its applications.

Ozone supports combustion, and combustibles can spontaneously ignite when placed in ozone and burn more violently than oxygen.

Summary. The state requires the ozone concentration of purified water to be between ozone solubility in water applications. The low value is used as the minimum concentration required for water disinfection and purification, and the high value is used as the achievable concentration value of "ozone water disinfectant".

Tap water ozone is opened, and the solubility value of the international standard is kept for 4 minutes, that is, the CT value is.

The residual ozone concentration in the water is kept at the effect for 5 10 min to achieve the purpose of disinfection.

What is the ozone concentration of purified water required by the national standard? The minimum amount can be sterilized!

Hello, shouting that I am a teacher of Xiaoxiang, an expert in education, an expert in education Q&A, I have consulted 1000+ people, I have seen your question, and quickly prepare the answer to the "National Standard for Pure Water Ozone Concentration" for you, give me two minutes of time code words, thank you Zheng Qianbi, please wait a while.

The state requires that the ozone solubility of pure water is between hail concentrations and water applications. The low value is used as the minimum concentration required for water disinfection and purification, and the high value is used as the achievable concentration value of "ozone water disinfectant". The ozone of the tap sail water is opened, and the international conventional standard is the solubility value of the acreage, which is maintained for 4 minutes, that is, the CT value is.

The residual ozone concentration in the water is kept at the effect for 5 10 min to achieve the purpose of disinfection.

Answer: Ozone (O3) is an allotrope of oxygen, which is a pale blue gas with a very different odor. The molecular structure is triangular, the bond angle is 116°, its density is times that of oxygen, and its solubility in water is 10 times that of oxygen.

Ozone is a strong oxidant, its redox potential in water, second only to fluorine (, its oxidation ability is higher than chlorine (and chlorine dioxide, can destroy the cell wall of decomposing bacteria, quickly diffuse into the cell, oxidize and decompose the glucose oxidase necessary for the internal oxidation of glucose in bacteria, etc., can also directly interact with bacteria and viruses to destroy cells, ribonucleic acid (RNA), decompose decomposition of DNA (DNA), RNA, stocking proteins, lipids and polysaccharides and other macromolecular polymers, The metabolism and reproduction processes of bacteria are disrupted. The killing of bacteria by ozone is caused by the rupture of the cell membrane, a process known as cell dissipation, which is caused by the crushing of the cytoplasm in water, and it is impossible for the cell to regenerate under the condition of dissipation. It should be noted that unlike hypochlorous acid disinfectants, the bactericidal ability of ozone is not affected by pH changes and ammonia, and its bactericidal capacity is 600-3000 times greater than that of chlorine, and its sterilization and disinfection effect is almost instantaneous, and bacteria can be killed when ozone is concentrated in water.

To achieve the same sterilization effect (e.g., 99% E. coli killing rate), the ozone water dose required is chlorine only.

Hello, High Ozone Sterilization Depth refers to the deepest penetration depth that ozone can achieve during the sterilization process. The clear point is that the depth of ozone sterilization at high concentrations depends on a number of factors, including ozone concentration, temperature, humidity, sterilization time, etc. In general, high-concentration ozone sterilization depths can vary from a few millimeters to a few centimeters.

Ozone sterilization is an efficient, fast, and residue-free sterilization method, which can kill various bacteria, viruses, fungi, spores and other microorganisms, and is widely used in medical, food, pharmaceutical, cosmetics and other industries. During the sterilization process, ozone destroys the cell wall and membrane of microorganisms through oxidation reactions, thereby achieving the purpose of sterilization. In addition to the high concentration ozone sterilization depth, ozone sterilization has several other characteristics.

For example, ozone sterilization does not produce chemical residues and is harmless to the environment and human health; Ozone sterilization is fast, generally only a few minutes to dozens of minutes to complete the sterilization; Ozone sterilization has a wide range of applications and can sterilize a variety of items. In conclusion, the depth of high-concentration ozone sterilization is an important indicator of the effectiveness and depth of ozone sterilization. In practical applications, it is necessary to select the appropriate ozone concentration, temperature, humidity and sterilization time according to the specific situation to achieve the best sterilization effect.
